A bus carrying the junior hockey team from the westerns Canadian town of about 6,000 people collided with a semi while traveling to a playoff game.

At least 13 other people on the bus were injured.

"The Humboldt Broncos' thank the RCMP for their work investigating the crash and determining what charges would be laid against the truck driver", the team said in a statement on Twitter. RCMP said he was initially detained, but was released and offered counselling. If convicted of unsafe operation of motor vehicle causing harm, he faces "upwards of 10 years", authorities said.

Sukhmander Singh, owner of the Calgary-based trucking company, said in April that the driver was going to the doctor and receiving counselling.

Investigators conducted more than 60 interviews and looked at every aspect of the collision, including speed, point of impact and environmental conditions.

"Our primary focus continues to be supporting the survivors, families and others that were directly impacted by the tragedy on April 6". A number of players who survived the crash are still recovering from significant injuries.
